I am using a gridview to display (open or save) files that have been uploaded into a SQL 2005 server. I have a templatefield within the gridview that contains a linkbutton that does a postback to GetUploadedFile.aspx that then fires the response.binarywrite() code. The code seems to work fine and opens/saves the files correctly. But once this has completed and I try and click on another button on the page, instead of doing the appropriate action it re-fires the getuploadedfile.aspx binarywrite code and opens up the "Open/Save/Cancel" dialog again.

View 3 RepliesI am generating a pdf file to a MemoryStream, and then using Response.BinaryWrite to display that in the browser. But if a pdf reader is not installed, then I get an ugly error message.
Is there something I can do so that if no pdf reader is installed, I can display a friendly message or provide the option to save the file to the system?
I'm using localReport to print PDF (SQL REPORTVIEWER). It works fine on localhost. When I move the application to Production (64 bits windows 2008) it gives me an error. (see below)
I put the renderedbytes in a Session in USERCONTROL and I do window.open('Program1.aspx')...
In page load of Program1.aspx I try to retrieve the Session variable and process.... I think this statement cause the error "Response.BinaryWrite (...) etc".
It works on my local pc (Vista 32bits)...

I have binary data - it is png picture.
I use Response.BinaryWrite to display this picture.
Unfortunately it works only in Internet Explorer. In Firefox and Chrome it shows long text of strange symbols.
What's wrong with BinaryWrite? How to solve this?
I may not say to asp:Image to show this picture, I may not indicate ImageURL, becouse there's no URL. This picture is response from webrequest. And webrequest may not be indicated in URL because I set some parameters not in QueryString but in post data.
How can I use response.redirect on button onclick or onclientclick event?

View 2 RepliesIs it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
View 5 RepliesI recently upgraded a web app to ASP.NET 4.0 , but I have to downgrade it back to 2.0, because the Response.Redirect from another web app, which is in ASP.NET 2.0, did not work.

What this code does at the end is Redirects to a direct download, and THEN afterwards, to a "tutorial page" on how to use the download. I can't seem to use these back to back. I've even used Response.Redirect(tutorialURL, false) so it wouldn't terminate processing, but it didn't work. It just STOPPED page processing. I've tried to use the Sleep() method of the Threading namespace, no luck. I'm sure there's an easy way to do this, I just don't know what it is.
I have an query when user select any option it should redirect and open new tab in same browser, actually it worked fine in firefox and IE but in chrome it opens a new window. Below is the code.

I have a site that uses authentication. I will be displaying links to other sites.Currently I am using Link Buttons because the link maybe to another site or a file in our DB so the Link Button allows me to place the DB id field into the command argument.So when the user clicks on one of the buttons I check to see if it match's a web site and if so I want to direct the user to the site. Here is the code.

strfile being the text of the button. This works, however it opens it in the same window which is less then desirable. I would like to open it in a new window. I have triedclient side scripting, I have tried process.start, and other ways to open the link in a new window. When I use these methods and I click on the button the page posts back but the link is never opened. I do have the Link Buttons inside a update panel and haveadded the button as a trigger with the same results. I have also moved the button out side of the update panel same results. Also the Link Buttons are inside a panel control.Another point this is being done in the code behind VB.net.
In one section of my site I have a response.redirect that calls a PHP script and returns to PDF file to a save/open dialog box.
This works -
Response.Redirect("http://webaddress.com/get_proof.php?rep=" & rep.ToString("000")
& "&filename=" & ViewState("sjobnoproof") &
"_s.pdf")
In another section i get the security warning from IE on the top. Users have to say yes and page refreshes and they to go back and do it again.
Response.Redirect("http://webaddress.com/get_ar.php?path=" & ViewState("reportsfranid")
& "_ADMIN/Client Files/Group" & ViewState("reportsgroup") &
"/" & ViewState("reportsrepid") &
"_" & ViewState("reportslastname") &
"&filename=" &
"CON_Modified.pdf")

How can I know seperate this array (controls) into singe strings?
I know this has been asked many times and have saw the posts that it cant be done and there are alternative solutions.
The caveat is that after clicking on the button this will load a new page with the target URL but I would want the current web form to remain as it is. That is essentailly two web forms side by side?
